Animate map camera around a point

Example

Animate the map camera around a point.

Creates an animated map to fly between different locations

Example

This example uses SDK JS to fly between different locations and visualize the frequency of US schools by location using a heatmap layer with low zoom levels and a styled circles layer with a data-driven property for zoom levels in more detail.
